Abstract :
A single-phase line-start synchronous reluctance motor (LSynRM) has merits of low cost, high efficiency, and reliability. The LSynRM has the unbalanced magnetic circuit caused by flux barriers and various shapes of conductor bars. Thus, the motor can cause the unbalanced starting torque with the initial starting position of the rotor This paper presents the design to improve starting performance of the LSynRM for household appliances. Design variables are the number and the shape of the conductor bars. The motor is analyzed by finite element (FE) analysis. A SPIM (single-phase induction motor) for mass production, a prototype, and a designed model of LSynRM are manufactured and tested.
